摘　　要：在保证鲜食玉米收获的同时,设计了一种安装在玉米收割台下部的秸秆粉碎装置,以实现玉米秸秆粉碎后还田。试验选取刀片数量、机器行进速度及粉碎轴转速为影响因素,通过理论分析得到机器行进速度与粉碎轴转速的取值范围,优化后得到粉碎刀片的数量及排列方式。以鲜食玉米的茎秆粉碎合格率为评估指标,进行二次旋转正交试验,并对试验结果进行响应面法优化分析。研究结果表明:各影响因素对鲜食玉米茎秆粉碎合格率的主次顺序依次为粉碎轴转速、刀片数量、机器行进速度,装置优化后的最佳工艺参数组合为:刀片数量16个、机器行进速度2m/s、粉碎轴转速1620r/min,理论鲜食玉米茎秆粉碎合格率为88.97%。While ensuring fresh corn harvest,design a straw pulverizer installed in the lower part of the corn harvest,realizing the grinding of corn stalks,the test selection,the number of blades,the speed of the machine,and the influencing factors,through theoretical analysis The number of pulverized blades is obtained by obtaining the value of the machine travel speed and the pulveroid axis speed,and the quantity and arrangement of the pulverized blade are obtained.The quantitative test of the stem pulverization was evaluated,and the secondary rotary orthogonal test was performed,and the test results were optimized by the response surface method.The results show that each influencing factor on the primary sequence of fresh food corn stalk pulverization qualification is:pulverized axis rotation speed,the number of blades,the machine travel speed;the optimal combination of the optimized process parameters is:the number of blades 16,machine travel speed 2m/s,pulveroid shaft speed 1620r/min,theoretical fresh food corn stalk pulverization qualified rate is 88.97%.
